Tata Power on Friday said the power failure in Mumbai earlier this week was due to cascade tripping at sub-stations and transmission lines of MSETCL. The company also said the MSTECL transmission system failure led to cascading impact on all the downstream suppliers of electricity including Tata Power and BEST (Brihanmumbai Electric Supply and Transport).
“The power failure was attributed to cascade tripping at sub-stations and transmission lines of MSETCL, the state-run transmission company, leading to grid failure at Mumbai that resulted in power outages on Monday morning, October 12th 2020,” a Tata Power statement said. It said a central team comprising officials from the Central Electricity Authority (CEA) is investigating the power breakdown in the city.
